I can see a couple of potential mistakes:
- Rare interaction with your executives
- Flooding them with unnecessary details
You should engage with your executives regularly (weekly basis is good0, and you should only give them headlines, they have too much work to do and they can't dedicate their whole work day just for you.
Leaving them for a while and then coming to them with your list of problems is a very bad idea. Involving them at a very high level is the best way to handle them, and they'll reward you with their support once they find out that you deserve.
- Keep them near
- Only give them headlines
